Adjustable chip breaker for a cutting tool

Abstract

This invention is directed to an adjustable chip breaker associated with a cutting tool having a cutting bit. The position of the chip breaker can be adjusted with respect to the cutting tool.

From the foregoing and having presented by invention, I claim: 
     
       1. A chip breaker for a cutting tool, said chip breaker comprising; a. a yoke having a base, a first arm and a second arm;   b. in an end view said yoke presenting the configuration of a U-member;   c. said first arm having a first adjusting means to assist in positioning said yoke;   d. a breaking member;   e. means to permit said breaking member and said first arm to move relative to each other;   f. said second arm having a second adjusting means to assist in positioning said yoke.   
     
     
       2. A chip breaker according to claim 1 and comprising: a. said means to permit said breaking member and said first arm to move relative to each other comprising a passageway to allow said relative movement; and,   b. a means to position said first arm and said breaking member with respect to each other.   
     
     
       3. A chip breaker according to claim 1 and comprising: a. said means to permit said breaking member and said first arm to move relative to each other comprising a passageway in said breaking member;   b. said passageway in said breaking member defining an inner side wall;   c. a slot in said inner side wall; and,   d. a means to position said breaking member with respect to said first arm.   
     
     
       4. A chip breaker according to claim 1 and comprising: a. said means to permit said breaking member and said first arm to move relative to each other comprising a passageway in said breaking member;   b. said passageway in said breaking member defining an inner side wall;   c. a slot in said inner side wall; and,   d. said first arm member comprising a tapped passageway in said first arm, and a set screw in said tapped passageway and in said slot; and,   e. said second adjusting means comprising a tapped passageway in said second arm and a set screw in said tapped passageway.   
     
     
       5. A combination of a cutting tool and a chip breaker: a. said cutting tool comprising: 1. a shank;   2. a head portion; and,   3. a cutting bit positioned on said head portion;     b. said chip breaker comprising: 4. a yoke having a base, a first arm and a second arm;   5. in an end view said yoke presenting the configuration of a U-member;   6. said first arm having a first adjusting means to assist in positioning said yoke on said cutting tool juxtapositioned to said cutting bit;   7. a breaking member;   8. means to permit said breaking member and said first arm to move relative to each other;   9. said second arm having a second adjusting means to assist in positioning said yoke on second cutting tool.     
     
     
       6. A combination of a cutting tool and a chip breaker according to claim 5 and comprising: a. said means to permit said breaking member and said first arm to move relative to each other comprising a passageway to allow said relative movement; and,   b. a means to position said first arm and said breaking member with respect to each other.   
     
     
       7. A combination of a cutting tool and a chip breaker according to claim 5 and comprising: a. said means to permit said breaking member and said first arm to move relative to each other comprising a passageway in said breaking member;   b. said passageway in said breaking member defining an inner side wall;   c. a slot in said inner side wall; and,   d. a means to position said breaking member with respect to said first arm.   
     
     
       8. A combination of a cutting tool and a chip breaker according to claim 5 and comprising: a. said means to permit said breaking member and said first arm to move relative to each other comprising a passageway in said breaking member;   b. said passageway in said breaking member defining an inner side wall;   c. a slot in said inner side wall; and,   d. said first arm member comprising a tapped passageway in said first arm and a set screw in said tapped passageway and in said slot; and,   e. said second adjusting means comprising a tapped passageway in said second arm and a set screw in said tapped passageway.
